What is Google Cloud Print?

With Google Cloud Print, you can print any document from anywhere to your Google Cloud Print connected printer.

When you print using Google Cloud Print, your file is securely transferred over the internet to your printer. Whether you are in the same room or even in a different country on a different continent you can print whatever you want using any device such as a smartphone, tablet PC or desktop computer.

Share with friends or colleagues

Google Cloud Print enables you to share your printer with friends, family or work colleagues with ease. From the Google Cloud management page you can share your printer securely with trusted individuals.

Scalable Printing Solution for Business

Google Cloud Print is used internally by Google employees on hundreds of printers and is designed to scale to your business demands, growing with your business or as a replacement for your existing printing infrastructure.
What is AirPrint?

Apple AirPrint allows full colour, top-quality printing from iOS devices such as iPhones and iPads directly from within many Apps available from the Apple App Store.

To take advantage of AirPrint, your compatible printer must be connected to the same wireless network as your iOS device or Mac computer.

AirPrint enables users to print wirelessly from within applications on Apple devices to AirPrint Compatible Printers connected to a wireless network. You can use your iPhone, iPod Touch or iPad to easily print via Airprint without the need to install drivers or configure the printer queue. Just tap 'print' and select your AirPrint compatible printer, and print!....It's that simple.

What You See is What You Print

If you can open it on your apple device, chances are you can print it with AirPrint and an AirPrint compatible printer. Airprint works with Safari, Mail, Photos, iWork, PDF's in iBooks and many third-party AirPrint compatible apps available from the app store.

Full list of AirPrint compatible printers

Third-Party Apps

There are also a wide variety of third-party apps available to enable wireless printing through Apple devices, even to machines that are not natively AirPrint compatible printers. By sharing a printer installed on an Apple Mac or Windows Pc over a wireless network any printer may be able to take advantage of the AirPrint features. (An additional third-party app may be required to be installed on the local machine)

*For full AirPrint support, a printer firmware upgrade may be required which is available directly from the relevant manufacturer website.

Whilst every effort has been made to ensure that the above information is correct at the time of publication, Printerland will not be held responsible for the content of any third-party software suggested on this site and usage of any such software is at the users own risk.
